Few people know why proteins are needed for the human body. By the way, these substances are very, very important. The thing is that muscle fibers are built from them, and various enzymes and hormones are created.
Proteins, along with carbohydrates, fats, water, minerals and vitamins, are substances necessary for the body. As noted earlier, muscle fibers are built from proteins. This occurs with the participation of proteins such as actin and myosin. It is thanks to them that muscle tissue has its own unique characteristics. At the same time, the construction of these proteins is possible only if there is an influx of proteins from the outside.
An equally important protein necessary for the life of any person is hemoglobin. Moreover, for its formation, protein alone is not enough. The fact is that this protein is iron-containing, and to build it, everything else needs this particular element. The main function of hemoglobin is the transport of oxygen to cells. Moreover, it is located in red blood cells, giving them the appropriate color.
Endocrinologists can tell a lot about why proteins are needed. The fact is that hormones are just proteins. These substances are responsible for the course of almost all processes in the body. They have a high activity and therefore a very small number of them can have a significant effect on tissues and entire organs. Examples of such hormones are the following proteins: adrenaline, dopamine, atropine, prolactin, progesterone, thyroxine, triiodothyronine, vasopressin and others. Every woman should know what proteins such as follicle-stimulating and luteotropic hormones are for. The fact is that they are responsible for regulating the menstrual cycle, and if their production is impaired, then conception of a child will become a real problem for the couple.
You can also talk a lot about why proteins are needed in the digestive system. Here they perform an enzymatic function. Proteins like pepsin and chemotrypsin help digest food that enters the gastrointestinal tract.
Protein deficiency is often experienced by those people who fundamentally do not eat animal products. The fact is that it is in meat that contains the largest amount of protein. At the same time, today meat products can become the choice of those who want to lose weight. For example, boiled chicken breast is a valuable dietary product. The so-called "Kremlin" diet has long been developed, which involves the inclusion of a large amount of meat in the diet (while vegetables, fruits and other products are present, but in a very small amount). On such a diet, a person can quickly lose extra pounds. It is worth noting that in foods of plant origin there are also proteins. Legumes (soy, lentils), as well as nuts, are most valuable in this regard. These products must be included in the diet of every vegetarian.
Many athletes consume protein in pills. However, they know exactly what proteins are for. So athletes quickly build muscle mass. Today, pharmaceutical companies offer a huge number of different types of similar products. Naturally, it’s better to pay a large sum, but buy a really good protein. Only in this case can we count on a rapid increase in muscle mass and the absolute safety of the drug for health.
